kernel: mm/slub: avoid accessing metadata when pointer is invalid in object_err()

A flaw was found in the Linux kernel’s SLUB memory allocator mm/slub. The function objecterr — used for debugging object metadata freelist pointer, redzone, etc. — can access invalid pointers when reporting corruption, leading to a crash. In some cases, due to freelist corruption e.g., detected b...

CVE-2026-74442

A flaw was found in the Linux kernel's drm/vmwgfx driver. This vulnerability occurs when the vmwvkmsinit function fails to initialize a workqueue, leaving a pointer as NULL. During module unload, the vmwvkmscleanup function attempts to destroy this NULL workqueue, leading to a kernel panic. A loc...

haproxy: HAProxy: Denial of Service via HPACK dynamic table insertions

A flaw was found in HAProxy. An attacker can trigger HPACK dynamic table insertions under memory pressure, leading to a null pointer dereference in the hpackdhtinsert function. This can cause HAProxy worker processes to crash, resulting in a denial of service DoS...

CVE-2026-74538

A flaw was found in the Linux kernel's Bluetooth ISO Isochronous Stream subsystem. A missing lock when accessing socket connection information within the isoconnectind function could lead to a null pointer dereference. This vulnerability could allow a local attacker to cause a system crash,...

CVE-2026-74445

A flaw was found in the Linux kernel's drm/vmwgfx component. A local attacker can trigger a null pointer dereference by sending a specially crafted command to the vmwcmddxbindquery function. This can lead to a kernel crash, resulting in a Denial of Service DoS for the affected system...

CVE-2026-74491

A flaw was found in the Linux kernel. A null pointer dereference vulnerability exists within the ofpcirangeparserone function. This occurs when ofmatchbus returns a null value for nodes with specific range properties, which is then improperly dereferenced. An attacker could potentially exploit th...

CVE-2026-72458

A flaw was found in the Linux kernel's Apparmor security module. This vulnerability occurs in the unpackpdb function, where it does not correctly handle a null pointer if a preceding operation, unpackdfa, fails. This oversight can lead to a NULL pointer dereference, which typically results in a...

CVE-2026-72373

A flaw was found in the AFS Andrew File System component of the Linux kernel. A missing NULL pointer check in the afsbreaksomecallbacks function could allow a local attacker to trigger a kernel panic, leading to a denial of service. This occurs when the afslookupvolumercu function returns a NULL...

CVE-2026-72490

A flaw was found in the Linux kernel's rtl8723bs Wi-Fi driver. An incorrect null-pointer guard in the rtwaesdecrypt function could lead to the system misinterpreting memory addresses. This issue may result in a system crash, causing a Denial of Service DoS. Mitigation Mitigation for this issue is...
